Taxonomy Of The Neotoma Albigula-Group Of Woodrats In Central Mexico, E. Raymond Hall, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Study of specimens collected from critical localities since 1944 reveals that: Neotoma montezumae and N. leucodon zacatecae are indistinguishable from earlier named taxa; N. latifrons is a subspecies of an earlier named taxon; and N. palatina, previously known from only one specimen and thought by some mammalogists to be merely an aberrant individual of Neotoma albigula, is a species distinct from N. albigula as Goldman tentatively decided when he named it 64 years ago. In the narial passage, the partition formed by the vomer that extends well behind the hard palate as a sword-like projection is present in …

Harvest Mice (Genus Reithrodontomys) Of Nicaragua, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Harvest mice of the genus Reithrodontomys first were reported from Nicaragua by Oldfield Thomas (1907), who originally described Reithrodontomys sumichrasti modestus based on a single specimen from Jinotega. J. A. Allen (1908, 1910) recorded additional specimens of R. s. modestus, which still was the only species known from the country when A. H. Howell (1914) revised the genus Reithrodontomys. In his thorough review of Latin American harvest mice, Hooper (1952) added a second species, Reithrodontomys mexicanus lucifrons, to the Nicaraguan fauna, and Englert (1959) and Anderson and Jones (1960) recorded three additional kinds. The present report treats …

Osteological And Mylogical Comparisons Of The Head And Thorax Regions Of Cnemidophorus Tigris Septentrionalis Burger And Ameiva Undulata Parva Barbour And Nobel (Family Teiidae), Don Lowell Fisher, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

The anterior osteological elements of the skull, lower jaw, and wrist along with the anterior myological characters discussed and figured in this report suggest that A. u. parva and C. t. septentrionalis are members of distinct groups which can be differentiated by internal morphologic characters. Although comparisons were restricted to highly geographically separated individuals of the same family, their general body form and structure appear to be similar.

A great number of anatomical structures are shared in common, but the significant differences between them include:

1. General skull appearance. The skull of C. is generally lighter, that is the bones …

Pinyon-Juniper Succession After Natural Fires On Residual Soils Of Mesa Verde, Colorado, James A. Erdman

Brigham Young University Science Bulletin, Biological Series

A mountain brush vegetation typified by Gambel oak (Quercus gambelii) and serviceberry (Amelanchier utahensis) dominates the uplands of Mesa Verde National Park. There is evidence that this brush element is a successional stage that has been maintained by repeated natural fires in a large part of the Mesa Verde landscape. This study was conducted to determine the role of fire in the region's ecology, the nature of the climax pinyon pine (Pinus edulis) and Utah juniper (Juniperus osteosperma) vegetation, and the major successional stages that lead to the climax condition.

The Development Of The Endogenous Stages Of Eimeria Ninakohlyakimovae (Yakimoff And Rastegaieff, 1930) In Domestic Sheep, Richard S. Wacha

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Forty-five mixed breed lambs, 1 to 4 months of age, were used to study the patent period and endogenous stages in the life cycle of Eimeria ninakohlyakimovae. The lambs were inoculated with oocysts of this species and killed at daily intervals from 1 through 14 days after inoculation. From all lambs of the study sections of intestinal tissue were prepared by routine methods for histological examination.

E. ninakohlyakimovaewas observed to have 2 generations of schizonts in its endogenous development. Mature, first-generation schizonts had an average diameter of about 290 μ and had many thousands of merozoites, averaging 11.9 …

Growth Of Eimeria Alabamensis From Cattle In Vitro And The Changes In Fine Structure Associated With Schizogony, J. Robert Sampson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Monolayer primary cultures of cells from bovine embryonic intestine (BEint), kidney (BEK), spleen (BES), and thyroid (BET) and cell line cultures of embryonic bovine trachea ( EBTr) and synovium (BESy)as well as established cell line cultures of Madin-Darby bovine kidney (MDBK), human intestine (Int 407), and Syrian hamster kidney (BHK-21) were inoculated with freshly excysted sporozoites of Eimeria alabamensis and observed for 4 days. Sporozoites penetrated all cell types during the first 24 hours in culture. Numerous intracellular sporozoites, trophozoites, and binucleate schizonts were seen in all cell cultures except Int 407. The best development occurred in BES and MDBK …

The Effects Of Formaldehyde On The Frequency Of Reversion Of The White-Ivory Mutant Of Drosophila Melanogaster, Ruth Ellen D. Wood

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study is an analysis of the effects of formaldehyde, a chemical which is both recombinogenic and mutagenic, on white-ivory (wⁱ) a highly mutable allele of the white locus of Drosophila. Formaldehyde is shown to significantly increase the reversion frequency of wⁱ. The results of this investigation differ from earlier observations in three respects: (1) there is a positive correlation between RNA (ribonucleic acid) concentration and reversion frequency in the presence of formaldehyde, but reversion does not appear to be totally RNA dependent; (2) female germ cells are more sensitive than those of the male; …

White-Tailed Deer In Southeastern Minnesota: Winter Observations, Robert D. Dorn

Journal of the Minnesota Academy of Science

Food habits, movements, vegetation type use, and bedding of white-tailed deer (Odocoileus virginianus borealis) were observed while snow-tracking in southeastern Minnesota. Waste corn (Zea Mays) was the most important food item. Three dogwoods (Cornus racemosa, C. rugosa, C. alternifolia), all non-commercial forest species, were the most important for browse. Acorns were unavailable due to crop failure. Six trails made in less than 24 hours covered more than 1 mile each, straight line distance. The longest was 31/s miles. Snow did not appear to affect movements. About two-thirds of the beds were on wooded uplands. Browsing areas appeared dependent on bedding …

Looking At Wolves As Scientific Subjects Rather Than As Storybook Villains, John Mcclung

Journal of the Minnesota Academy of Science

Minnesota researchers, attempting to separate objective data about timber wolves from emotional attitudes, are compiling information gathered over a period of several years in the state's north woods. Findings suggest that laws to protect and preserve this animal may be as necessary as programs to control predations on deer or domestic livestock.

Survival Of Hand-Reared Mallards (Anas Platyrhynchos) On Artificial Farm Ponds, Lawrence L. Thomforde

Journal of the Minnesota Academy of Science

The survival of hand-reared, game-farm mallards released on artificial farm ponds was studied in Goodhue County, Minnesota. Of the 300 ducklings released each year from 1965 through 1967, an average of 45 per cent survived until most were capable of flying. More ducklings survived when released on ponds fenced from livestock than on unfenced ponds. Grazing livestock severely reduce cover vegetation around unfenced ponds. A total of 3.7 per cent of the bands were recovered. The first year recoveries represent 64 per cent of all the bands reported. Thirty-nine per cent of the band recoveries occurred within 15 miles of …

Movement Of Franklin's Ground Squirrel Into Northeastern Minnesota, Jerome D. Robins

Journal of the Minnesota Academy of Science

Specimens of Franklin's ground squirrel have been obtained in several localities in St. Louis County, Minnesota. The movement of this prairie-dwelling rodent into the montane coniferous forest region of northeastern Minnesota may be related to recent man-made changes in the habitat.

Bats Of The Genus Myotis From Western Mexico, With A Key To Species, J. Knox Jones Jr., Hugh H. Genoways, Larry C. Watkins

University of Nebraska State Museum: Mammalogy Papers

Distribution and variation in Mexican representatives of the vespertilionid bat genus Myotis have not been well documented. The most complete modern systematic treatment of these bats is that of Miller and Allen (1928), although these authors examined relatively few specimens and some of their taxonomic conclusions have been modified by more recent studies (see especially Findley, 1960; Findley and Jones, 1967; Genoways and Jones, 1969). In the past two decades, field representatives of the Museum of Natural History at The University of Kansas have obtained large collections of mammals in western Mexico, principally in the states of Jalisco and Sinaloa. …

Some Ecological Relations Of Fairy Shrimps In Alkaline Habitats Of Nebraska, D. B. Mccarraher

Nebraska Game and Parks Commission: Staff Research Publications

Ecological studies on the distribution of fairy shrimps have been made from 246 sites in the sandhills region of Nebraska. New records for Nebraska have been established for Artemia salina, Branchinecta campestris, B. lindahli, B. mackini and Cyzicus mexicanus. Seasonal populations of shrimp have been located in habitats containing permanent fish populations. Water mineralization was the dominant environmental condition related to the distribution of phyllopods with sodium and potassium compounds predominating in the strongly alkaline lakes. Several of the Artemia lakes were classified as hydroxide sites. Many of the alkaline ponds, where B. lindahli and B. campestris flourish, are …

Incidence Of Trematode Infection Of Snails In A Small Minnesota Lake, Ellen Shaffer

Journal of the Minnesota Academy of Science

The study on which this paper is based was a preliminary effort to determine three factors: (1) the nature of the snail and trematode fauna of a small lake, (2) the incidence of trematode infection in the snail population, and (3) possible changes in the incidence of trematode infection in snails at various periods in a single summer.
